Python [WinError 193] %1 is not a valid Win32 application

Question

I installed wordcloud

pip install wordcloud

Then I imported wordcloud

import wordcloud
import numpy as np
from matplotlib import pyplot as plt
from IPython.display import display
import io
import sys

I got this error:

I resolved problem.

I uninstalled Anaconda
I deleted Python folder in : C:\Users\Admin\AppData\Roaming
I removed .conda folder in C:\Users\Admin
I installed Anaconda
I insert into C:\Windows\System32, pythoncom38.dll and pywintypes38.dll from C:\ProgramData\Anaconda3\Lib\site-packages\
I uninstalled wordcloud and Numpy, then installed

pip uninstall wordcloud
pip uninstall Numpy
pip install wordcloud
pip install Numpy

Numpy that you have installed doesn't have correct libs for ctypes. Probably it is 32bit version, and your system has 64bit architecture or vice versa. Or you lunching it with incompatible python interpreter. Please try to lunch it with both, 32 and 64 bit python interpreter.

I lunch it by `jupyter notebook` – Beso Jan 03 '21 at 13:03
Try deleting(or temporary remane it) ctype folder at `C:\ProgramData\Anaconda3\lib\ctypes\` – George Jan 03 '21 at 13:13
